Title: Improvements relating to crucibles or melting pots
IPC: F27B14/10
Filed: 1940-07-02
Abstract: 542,324 Crucibles. LEWIS, E. C., and STONE & CO., Ltd., J. July 2, 1940, No. 11135. [Class 39 (iii) ] Crucibles or pots employed for melting magnesium or magnesium-base alloys are protected from external deterioration by a surrounding container b. The exterior of the pot a is formed with grooves to receive the tubes d for the heating medium, which may be an electric resistance. The remaining space g is filled with a good heat conductor such as an iron cement, or a mixture of sodium silicate and iron filings. The bottom of the pot may be heated by a similar heater d. which is pressed into contact with the pot by an adjustable ring l. The heating element may be divided into lengths extending around half the pot a, each having its own terminals and each may be controlled by a thermostat. The ends of these lengths extend into slots n in the container b, the open ends of the slots being connected by plates o. The parts are assembled in an inverted position, so that the container b presses the tubes d into contact with the pot a. In case of breakage of the crucible, molten metal flows into the cement-filled space, and no explosion occurs.

Title: Injection process and injection device for internal-combustion engines with fuel injection
IPC: F02M59/10
Filed: 1955-04-25
Abstract: 792,775. Fuel injectors. SATZGER E. April 25, 1955 [April 27, 1954], No. 11840/55. Class 7(3) In a fuel injection device arranged to produce preliminary and main injections, the main injection is initiated by the pressure in the combustion space. In Fig. 1 the fuel is supplied to an injection space 5 past a non-return valve 4 and preliminary injection occurs through a fine orifice 6, the main injection orifice 8 being closed by a spring loaded valve 9 which is provided with a recess 12 on which acts the pressure in the combustion space transmitted through the orifice 8. At a predetermined combustion space pressure the valve 9 is lifted off its seat and the main injection through orifice 8 takes place, the valve 9 being maintained,raised for the remainder of the injection cycle by the pressure in chamber 5 acting upon the end of the valve. In a modification the valve 9 is provided with an annular step on which the pressure in space 5, which increases with engine speed, acts to assist the valve 9 to open and to cause the valve 9 to open at a lower combustion space pressure with increasing speed; alternatively the pressure in space 5 may be arranged to assist the spring 11 in loading the valve 9, whereby the valve 9 opens at a higher combustion space pressure with increasing engine speed. The valve 4 is arranged so that on closing it reduces the pressure in the space 5 and prevents drip. In Fig. 5 the preliminary injection takes place through passages 18, 19, in the valve 9<SP>111</SP> which directs the preliminary jet through the main injection orifice 8. In a further modification, Fig. 6, the non-return valve 4 is replaced by a spring-loaded valve 21, concentric with the main valve 9<SP>1v</SP>, which is lifted by fuel pressure before the valve 9<SP>1v</SP> is opened and permits the fuel to reach the preliminary orifice 6. The valve 21 may be arranged to contact a collar 20 on the valve 9<SP>1v</SP> to assist opening of the latter; alternatively the loading spring of the valve 9<SP>1v</SP> may be arranged inside the valve 21 so that the force of the loading spring is reduced as the valve 21 opens, the amount of the reduction varying with the varying lift of the valve 21 at varying engine speed.

For surgical use, a further two-part sterilizable cover 40 is fitted by means of a bayonet joint, a knurled ring 41 being connected by a screw passing through a slot to the inner sleeve 26 to operate the cam disc. A recess in the sleeve 26 is engaged by a spring-pressed ball to retain the detents 18 in the closed position.

Abstract: 510,628. Producing tubes on push-benches. STEWARTS & LLOYD'S, Ltd., and McLAY, G. S. April 20, 1938, No. 11882. [Class 83 (iv)] In a push-bench method of producing a metal tube a hollow billet or blank with an internally constricted formation at or towards one end is reduced on a mandrel which bears directly or indirectly against the constricted part of the billet. The billet or blank is made hollow in a rotary piercing apparatus and is deformed at a number of points 3 at its end to provide internal shoulders 4 against which a plug 5 with a shouldered portion and a stem 9, adapted to project through the hollow billet 1, is seated. The mandrel 6 then bears against the end of the plug to force the billet, which may have a bevelled end 14, through dies 11 or non-driven rollers. When the tube has been made to the required dimension the stem 9 of the plug may be gripped to pull the tube off the mandrel and the plug subsequently removed by sawing through the thin part of the tube adjacent the shoulder on the plug. The tube may first be loosened on the mandrel by passing it through rollers.

Abstract: 1515594 Improving green strength of tyre blanks POLYSAR Ltd 26 March 1976 12215/76 Heading B7C In the manufacture of a pneumatic tyre including a plurality of carcass plies having parallel cords, e.g. of steel, rayon, glass, nylon, polyester, or cotton, arranged at a cord angle of 75-90 degrees to the mid circumferential plane, the uncured rubber of each carcass ply comprises a synthetic rubber having labile cross links to provide green strength thereto, the synthetic rubber being an SBR rubber containing bound tertiary amine groups in the polymer chains, the polymer having been reacted with a dihalogen compound which reacts with the amine groups. The uncured carcass rubber allows the assembled carcass (including bead cores and an inner liner) to be expanded from a cylindrical state into its toroidal state without an undue loss of strength in the carcass rubber. The carcass ply rubber may also include natural rubber and/or other synthetic rubber. The tertiary amine group may contain monomers, e.g. dimethylaminoethyl. The other synthetic rubber may be polybutadiene or butadiene-styrene. Many examples of dihalogen compounds are given in the Specification, as are specific examples of the amounts of the ingredients for the carcass ply rubber. The cords of the carcass plies may be treated with adhesive to improve their adhesion to the rubber of those plies.
